Brenden Aaronson is the first new arrival at Elland Road during this summer's transfer window after the £25 million US international signed a five-year deal.
The 21-year-old joins from Austrian champions FC Red Bull Salzburg and arrives with a blossoming reputation in his homeland as an up-and-coming fixture of the United States soccer scene.
His £25 million addition places him among Leeds' most expensive purchases and also makes him the second-costliest American in football transfer history, second only to Chelsea's Christian Pulisic.
Here are the ten most expensive signings in Leeds United's long and storied history.
7. 4. Rio Ferdinand: £23.5m
